A study on lahar as a substitute for ordinary river sand as a fine aggregate in the production of reinforced pipe culverts.

The research has included the determination of the effects of substituting lahar sand to ordinary river sand as a fine aggregate material in the production of commercial reinforced pipe culverts. Five types of specimen were manufactured and tested in order to find an approximate optimum percentage c...

Ortiz, Cheriss T. San Juan, Julius Edgar B. Uy, Cloyd Raymund A. The research has included the determination of the effects of substituting lahar sand to ordinary river sand as a fine aggregate material in the production of commercial reinforced pipe culverts. Five types of specimen were manufactured and tested in order to find an approximate optimum percentage composition of both lahar sand and ordinary river sand. To note the effects of changing the composition of the fine aggregate in the concrete mixture, varying concentrations of lahar and river sand were used. The composition of fine aggregates in the culverts we tested were 100% lahar sand, 75% lahar sand with 25% of ordinary river sand, 50% of lahar sand with 50% of ordinary river sand, 25% of lahar sand with 75% of ordinary river sand, and 100% ordinary river sand. Tests were conducted in order to get the permeability and tensile strength of the different kinds of reinforced pipe culverts. The chemical and physical properties of both lahar sand and ordinary river sand were also researched upon in order to have an additional basis on the analysis of this research. Some of the physical properties that were tested were the moisture content, specific gravity and grain size distribution of both materials. The group discovered that the use of 100% lahar sand as fine aggregate in pipe culverts would be cheaper, less permeable, but most importantly, produce a greater ultimate tensile strength than the use of ordinary river sand. 2000-01-01T08:00:00Z text https://animorepository.dlsu.edu.ph/etd_bachelors/10359 Bachelor's Theses English Animo Repository Volcanic ash, tuff, etc. Aggregates (Building materials) Civil Engineering
